Winchester Ammo Sup400 Super Suppressed 400Legend 300Gr Open Tip 20 Per Box/10 Case

Winchester Super Suppressed ammunition in 400 Legend delivers the clean, quiet performance you want from a suppressed rifle. These 300-grain open tip rounds are engineered specifically for shooters running suppressors, combining subsonic velocities with Winchester's legendary reliability and accuracy. Whether you're hunting with a suppressed setup or running suppressed range sessions, the Super Suppressed line gives you consistent performance while minimizing the fouling that typically builds up in both barrel and suppressor.

The encapsulated bullet design—where the copper jacket fully encloses the bullet core—is the key to keeping your suppressor and barrel cleaner than standard ammunition. That design choice matters if you're shooting suppressed regularly; less lead shedding means fewer carbon deposits and easier maintenance on both your rifle and suppressor. You get reliable, accurate performance in both suppressed and non-suppressed firearms, so if you ever shoot the same gun without a can, these rounds won't let you down.

Each box contains 20 rounds, and we carry cases of 10 boxes, so you can stock up on quality suppressed ammunition without breaking the bank on shipping or hunting trips. If you're building out a suppressed hunting or range rig in 400 Legend, Winchester Super Suppressed should be on your short list.

Frequently Asked Questions

Will Winchester Super Suppressed 400 Legend work in non-suppressed rifles?

Yes. While these rounds are optimized for suppressor use, they deliver reliable and consistent performance in both suppressed and non-suppressed firearms.

What makes these rounds better for suppressors than standard ammunition?

The encapsulated bullet design encloses the bullet core in a copper jacket, which significantly reduces lead fouling inside both your barrel and suppressor. That means cleaner operation and easier maintenance if you're shooting suppressed regularly.

Are these subsonic rounds?

Yes. These rounds are loaded to subsonic velocities—below the speed of sound—which produces lower decibel levels when fired through a suppressor.

How much ammunition is in a case?

Each case contains 10 boxes of 20 rounds, for a total of 200 rounds per case.
